Air stone bubble trap

[charlesr1958]

With very small tanks, such as my two litre desk top tank, there was always the problem of providing aeration which for small tanks, is best done, or easiest done with an air stone. But an airstone can make a big mess with saltwater spray from the bubbles popping on the surface. To avoid fix that problem I simply trap the bubbles. This could of course be used on larger tanks that still want to use airstones.
